Hi i am using the IOT2000 IO module on the IOT2040.I need to control a motor using PWM .The manual for the IOT2000 IO module says that D9,D10 and D11 maps to digital inputs DI3,DI2 and DI1 on the IO module .PWM is possible on D9,D10 and D11 as per the IOT2000 operating instruction manual .How is PWM possible on the digital inputs?

I understand that PWM is possible on D9,D10 and D11 pins ,but In the IO module these pins are designated as Inputs so how can i get a PWM signal on the Input.In Node red the intel_gpio node also has a PWM option which acts as an output node but since D9,D10 and D11 are inputs i am not able to do the PWM through the IO module.

According to the specification of the IO module:

Switching rate

Resistive load/lamp load: 10Hz

Inductive load: 0.5 Hz

This means even if the respective IoT2000 output pins would support PWM this is not supported by the hardware of the IO-module (PWM normally uses frequencies in the range of 500 Hz to 200 kHz).
